Limitations in the quality of transformation rates used with water quality models such as QUAL2K have led to the need to identify methods that can effectively and accurately determine these rates. During the early stages of method development of a Utah Department of Environmental Quality (Utah DEQ) funded project seeking to identify such methods, it was determined that under certain situations external carbon amendment may be required to successfully determine denitrification rates.
The focus of this study was to evaluate the potential impacts that introducing external carbon sources may have on estimating the laboratory denitrification rates resulting from these methods. Ultimately it was shown that, carbon amendment does not negatively impact the comparability of laboratory-generated rates to those that could be measured using in-situ methods. Additionally, it was determined that the Substrate Chemical Product method discussed herein should be used along with a no carbon, glucose, and sodium acetate amended treatments. After analysis of the data, the highest rate should be used if differences caused by carbon amendment can be identified.
